Jack Garland, the protagonist of Stranger of Paradise, has been recently announced by Square Enix to be the latest character to join the Dissidia Final Fantasy Opera Omnia roster. The character will be part of the Act 3 Finale and will bring a new unique mechanic while joining the ranks of the Warriors of Light (or clashing swords with them).

Jack is going to be a physical attacker who uses Greatsword weapons. The character has a major gimmick revolving around Negative Bravery which is based on his own stats. Negative BRV will trigger after BREAK status is reached with Jack, preventing enemies from dealing damaging HP attacks. Enemies essentially need to recover their BRV beyond 0 to be able to deal HP damage.
